1.4 Billion Beacon Towers

The first bells sounded from deep within the earth's crust. 1.4 Billion light screens suddenly light up on everyone's retinas. In the center of the light screen, a low wooden tower drawing floats quietly. Uncle Zhang on the street corner built an arrow tower. Programmers in the office building built electromagnetic turrets. The retired math teacher across the street drew a rune matrix for automatic aiming. Chen Mo only has one wooden pagoda. The next day, there was a stone tower next to the wooden tower. On the third day, an iron tower was erected next to the stone tower. On the fourth day, the iron tower extended westward, bordering the neighbor's earthen tower. Earthen towers connect brick towers throughout the street. Above the brick tower is the steel matrix of the entire city. The first wave of beasts rolled up on the western skyline. The surging dust of beasts blocks the sunlight. When the dust cleared, 1.4 Billion towers were connected in a line. That line is called the Great Wall.
